mourn-CONTROL SYSTEM.

AToaZZ whom it may concern: J Be it known that we, HERMAN W. FALK like, it is necessary that some means be pro vided for introducinginto the carbureting'v ohambera relatively volatile fuel, as in order that the enginemay be started and in order that after it has been started it may operate, it may have to be heated up to that point at which the heavier, less volatile fuels may be economically used. With this end in view, .we have provided means for first supplying the reservoir and thus the carbureting 'chamber with gasolene and subsequently discontinuing the supply of gasolene and supplying it with kerosene. f

provements in carbureters and has for one objecttoV .provide means for feeding to the carbureter a plurality ofdif'ferent kinds of liquid fuels. y i AIt is illustrateddiagrammatically in the 'accompanying drawings, wherein'- Figure 1 isa .plan view with parts removed; Fig.'2, a; section along the line 2-2 of. Fig. 1; Fig. 3,:a section along the line 3-3 of Fig. 1; Fig. 4, a section along the line 4 4 of Fig. 1; Fig. 5, a section along .theline-- of Fig. 2; Fig. 6, a diagrammatic View.

Like parts are indicated by like letters vvk.throughout the several figures.

` The carbureter A contains the vacuum or carburetingchamber A1 separated from the fuel reservoir A2 by the partition wall A3 inwhich -is mounted' the needle valve A4 to control the flow of combustible liquid from the yreservoir to the carbureter.

The reservoir A2 is provided on one side withv the supply well B and the overflow well B1`separated one from the other by the wall i B2 and from the remainder of the chamber A2 `by the wall B3. The chamber A2 is prof f f vided with the substantially conical horizontally disposedV partition wall B1 which divides the chamber into upper and lower sections. ITh'e'wall B4 is centrally perforate,

the perforation containing the removable collar B5 which'surrounds the ybarrel of the needle valve A4. The passage B6 leads from thebase of thesupply well B through the wall B3 into the interior of the lower portion of the receiver A2 beneath the partition wall B4. The overflow well B1 communicates with the upper portion of the reservoir above the partition wall B4.

lThe valve C which is rigidly attached to the carbureter wall by the cap screw C1 is provided with the supply and discharge pipes C2, O3 communicating respectively through the ports C4, C5 with the wells B, B1. The hollow conical valve C6 is rotatably mounted in the conical valve seat C7 being held in positionby the paclng C8 and nut C9 and 'is adapted to be turned by means of the handle C10. The conical valve C is provided with the two radially disposed passages C11', C12 leading from the hollow interior of the valve to the conical seat and being at right angles to each other, that is to say, separated by approximately ninety degrees. These passages which are located inthe plane of the passage C2 are adapted at times toy be in register with this passage which continues through to the'valve seat C7.

'-The curved passage D inthe wall of the valve c'asing'communioates at one end with the supply lpassage C2 intermediate the carbureterA and theconical valve C6 and at the other end with the vertically disposed gasolene supply pipe D1. The passage D2 communicates at one end with the interior of the conical yvalve C6 and at the other end with the vertically disposed kerosene supply pipe D3. vThe curved passage D4 communicates at one end with the vdischarge passage C3 and at the other end with the conical valve seat C7 in substantially the same plane as thel passage".v The passage D5 communicates at one end with the passage D4 intermediate its two ends and at the other with the Voverflow pipe D6. v

The valve casing is provided on its upper side `with the semicircular plate E project- -ingfrom the shank E1 in which is located valve fordifferent operative conditions.

We have illustrated in connection with the V-fuel reservoir a water reservolr F substantially similar in construction to the fuel reservoir, yhaving the needle valve F1, the supply well F2 and discharge well F3, communicating respectively with thefsupply pipe F t and discharge pipe F 5. Y

We have indicated the carbureting chamber as being controlled at one end by the circular valve FG and discharging at the other end through the sleeve FT to the engine not shown. The reservoirs A2 and F are inclosed by the cover F8 and provided with the port holes F9 closed by the covers F1o held in position by the springs Fllvabout the shank of the needle valves.

The pump Gr which is diagrammatically shown is driven from the engine shaft G1 and forces kerosene from a reservoir not shown through the kerosene supply pipe D3 into the valve housing C, the overflow returning through pipe D6 to the reservoir.V

The hand pump G2 is adapted to pump gasolene from the reservoir not shown throughl the gasolene pipe D1 to the valve housing C. The valve G3 is provided in the gasolene supply pipe D1 to shut off the gasolene supply whenV itlis necessary. n It will be evident that while we have shown in our drawings an operative device, still many changes mightbe made in size, shape and arrangement of Vparts without departing materially from the spirit of our invention, and we wish therefore that our drawings be regarded as in a sense diagrammatic.

The use and operation of our device are follows: In operating our engine, when the engine is stopped the carbureter will be, Y

by certain means subsequently to be de scribed, drained of its fuel supplyand therefore when it is desired to start .the engine the carbureter will be found free from any fuel whatever., The valve handle will be turned to theright until it co-incides with theletters Gas on the flat plate at the top of thevalve. This will bring one of the ports in the conical valve into register withthe curved discharge passage in the valve housing vand will at the same time shut 0E the supply passage from the interior of the conical valve. Gasolene will then be forced through the gasolene supply passage, out through the curved supply passage, thence into the supply'well, through this well, through the port at its bottom into the interior of the reservoir.- The forcing will continue until the gasolene completely ills the lower por# tion of the reservoir and yis about to, or actuallyfdoes overflow over the removable ring'kab'out the needle valve.` will then be started in the usual manner and Meanwhile, kerosene will be fed by any suitable means, preferably responsive vto the rotation of the engine, but here notV shown, up to the interior of the conical valve. It will then pass through the port therein, in reglthe gasolene is about to be exhausted, the

The engine will use the gasolene in the supply reservoir. Y

ister with the discharge passage and return to the supply reservoir through this discharge passage. After Vthe engine has beenV running andl has been well heated up and valve will be rotated until the handle coifncides with the letters Ker, thus bringing one of the ports in the valve into *register with the supply pipe and shutting olf the discharge pipe from the interior of the valve. The fuel will then be pumped'up through the conical valve, through the port into the discharge pipe and henceY to the base of the supply Well.. It will pass through the port at the other side of this base into the interior of the reservoir, filling the reservoir andl overflowing over the overflow ring about the nozzle barrel'. The overflow will then pass down into the discharge or overflow well and pass out through the overflow passage into the overflow pipe. It i will be noted that the supply well is open at the top and communicates with that portion of the reservoir which discharges into the overflow well, thus, in case of any stopping up of the lower portion ofthe reser voir the fuel will be able to escape back intoA the discharge. VIt will be noted also that by. the arrangement shown, the lower portion of the fuel reservoir which is, in communicav tion with the carbureting chamber throughv the'needle valve iskept constantly filled withV the combustible liquid and since the liquidf immediately overflows as soon as it reaches a height about that of the overflow ring, the "v level of the .liquid is always constant. In case it is desired to change the level of the fuel another ring may be substitutedof different height. Vhen the engine is stopped it is of course, necessary to drain the.` carbureting chamber and this is done by mov-V ing the Vvalve into the Vstop position,rthus bringing one ofthe ports iny the valve into. register with the supply Aand the other into register with the discharge, andA since the supply communicates with the bottom of the reservoir, kthe liquid will drain from lthe bottom through the conical valve into the discharge. p Y
